  • CHARGE ORDERED VERTICAL TRANSISTORS
    Publication number: 20160155941
    Abstract: A vertical charge ordered transistor is disclosed. A thin charge ordered layer is employed as a tunnel barrier between two electrodes. A gate-induced accumulation of charge destabilizes the charge ordered state around the circumference of the device, opening up a parallel ohmic conduction channel, which leads to an exponential increase in source-drain current. VCOT devices have the potential to exhibit very large on/off ratios, low off-state currents, and sub-threshold slopes below 60 mV/dec.

  • Methods and structures for electrically coupling a conductor and a conductive element comprising a dissimilar material
    Publication number: 20070155149
    Abstract: Methods and structures are provided for electrically coupling a conductor and a conductive element comprising a dissimilar material. A method for electrically coupling a first element comprising a first conductive material to a conductor formed of a dissimilar second material comprises cladding a second conductive element with the conductor. The second element comprises a facilitator material that facilitates the melting of the dissimilar material. A third element comprising a third conductive material that is metallurgically compatible with the facilitator material is cladded with a fourth element comprising a fourth conductive material that is metallurgically compatible with the first conductive material to form a connector. The fourth element is welded to the first element and the second element is welded to the third element.

  • Water purifying unit
    Publication number: 20020100721
    Abstract: A water purifying unit having a unique construction which enables it to be easily manufactured, assembled and serviced. The construction of the unit is such that it can with stand increased water pressure levels and is thus less prone to damage from water hammer.
